ok, I play halo reach’s firefight mode under matchmaking almost exclusively, and for the past two days, on ANY map, the second theres a few dead covenant, the framerate becomes extremely jerky, and sometimes the control command to response timing lags, eg I move to sidestep and a second later the character onscreen sidesteps.
every other mode but matchmaking plays as always, just fine.
the framerate has at times gotten bad enough its gotten me killed in situations I’d otherwise be able to get myself out of just fine.
I’m playing the downloaded edition of halo reach, with only the anniversary mappack.
edit:
I’m deleting both off my xbox harddrive and redownloading to see if that makes any difference.
I will also see if using the disc version of the game does anything.
